Escape Room Puzzle Tutorial - The "Fortune Teller's Crystal Ball"

Описание: In this video tutorial, I'll explain how to create a "Fortune Teller's Crystal Ball" escape room puzzle that uses the built-in touch input of an ESP32 microprocessor to detect when players place their hands on certain tarot cards. As they touch the cards, a crystal ball illuminates, using a MOSFET to gradually increase the current through a 12V LED lamp, and a sound effect plays through a serial MP3 player. When they touch the final card in the correct sequence, a relay is energised, releasing a maglock, allowing them to claim their prize.

I'll give a complete rundown of all the components I use, together with a detailed explanation of the wiring and code. More details and downloads for this tutorial, and all the other #EscapeRoom projects on this channel, can be found on my Patreon page at   / playfultech

If you're using an Arduino, Raspberry Pi, or other microcontroller that doesn't have touch-enabled inputs, you can add them using a capacitive touch module such as a CAP1188, as demonstrated in this tutorial:    • Arduino Capacitive Touch-Free Touch Sensor...
